As the demand for aesthetic orthodontic treatment increases, the use of self-ligating ceramic brackets is increasing. For stable treatment, there should be no fracture or deformation of the self-ligation ceramic bracket door. Therefore, considering the situation in which labial displacement of teeth occurs in the orthodontic treatment stage. For this study, a model of the mandibular anterior region of a ceramic self-ligating bracket with a passive sliding door mechanism was selected. The measured tensile force data was substituted into the simulation analysis conditions, and the tensile force, stress distribution, and deformation values were analyzed using the finite element method. Using this, it is able to use the design elements of the orthodontic bracket that should be considered as design inputs in the development stage.
